Abstract
The invention relates to a rapid repairing method of a rotary kiln, relating to the field of cement production. The rapid repairing method aims at solving the problems that the cost is low, and a roller axle is damaged owning to the vibration of a repairing device in the prior art. The repairing method comprises the steps of firstly, directly adding cooling water into a roller bearing bush; secondly, using a triangular scraper firstly, and then scrapping and grinding the individual highest point of a metal raised layer of an axial plane of a roller by using a cloth grinding wheel; thirdly, finely lapping the axial plane of the roller by utilizing an oilstone; fourthly, turning the rotary kiln slowly, adding cooling water in the roller continuously, and simultaneously, sprinkling little roller oil; and fifthly, after the check, adding high-viscosity oil for the roller, and enabling the rotary kiln to produce by feeding materials gradually. The rapid repairing method has the advantages that 'the cloth grinding wheel for a machine+oil soluble water tile lapping method' is creatively adopted for emergency treatment, the damage on the axle is small when the time is saved simultaneously.
Description
Technical field
The present invention relates to field of cement production, relate in particular to a kind of rotary kiln fast repairing method.
Background technology
In the clinker production line, wherein rotary kiln is " heart " equipment, and the quality of its operational situation directly influences the output and the benefit of full factory whole production line.Support roller is the important composition parts of rotary kiln supporting device; Cylinder of rotary kiln is played axially and the radial location effect, cylindrical shell can steadily be turned round safely, 3 grades of 12 support rollers are bearing the total weight of rotating part; Tens tons of average every bearing shell bearing loads; And in operation process, often receive the influence of cylindrical shell shock loading and adjustment, thereby heating of bearing bush of supporting roller high temperature and tile kilning phenomenon often easily take place, the processing method of generation tile kilning can only be to stop behind the kiln watt scraping again in the past; And handle and generally all to need the time about 3 days from the kiln temperature scraping bearing shell that cools down; Wait again kiln again firing up, feed intake and need the time more than 1 day, bring to production to have a strong impact on, simultaneously economic benefit is brought very big loss.
China's application number is a kind of utility model " the online prosthetic device of rotary kiln carrying roller " of 200920102836.7; A kind of online prosthetic device is disclosed; But this device mainly is that online turning reparation is carried out on the support roller surface, and steady to prevent the not round rolled portion that causes of support roller, this device need add independently repair system; Say from another angle, improved production cost again.In addition, this system in use owing to the vibrations of repair system itself, tends to supporting-roller shaft is caused damage.In addition, if the installation site at work owing to during stressed deviation to some extent, often cause the supporting-roller shaft axial plane to become off-centre operation easily.
Summary of the invention
The object of the invention solves technical costs height in the past exactly, and the vibrations of prosthetic device itself bring the problem of supporting-roller shaft damage.
Method step of the present invention is following, and step 1 directly adds cooling water in the bearing bush of supporting roller, lets the bearing bush of supporting roller temperature reduce to rapidly below 40 ℃; Step 2 is earlier carried out scraping with triangular scraper with indivedual peaks of the axial plane metal protuberance layer of support roller, installs machine with the handhold mini-size polishing machine then and polishes with fabric disc again, and is smooth, smooth until what polish the axial plane metal protuberance layer of support roller; Step 3 utilizes oilstone axial plane to support roller under the kiln slow-speed to carry out lappingout, till being smooth to the touch; Step 4, rotary kiln is played slow-speed, continues in support roller, to add cooling water, and drenches a little support roller oil simultaneously, and the time was greater than 1 hour; Step 5, inspection are confirmed in the support roller to add the bigger support roller of viscosity with oil behind no any foreign matter, the rotary kiln production that feeds intake, and the fast and inventory of kiln slowly increases up to returning to normal production.
Cooling water is directly added in the bearing bush of supporting roller among the present invention, need new tugboat oil be injected from observation panel before, open the bearing bush of supporting roller fuel outlet simultaneously, reduce to the 50-70 degree until temperature.The handhold mini-size polishing machine is installed machine and is polished with fabric disc, and it is inhomogeneous to prevent to polish, the damage support roller.Rotary kiln cools off under the slow-speed state, refers to the cooling of bearing bush of supporting roller water, grinds, and in water, drench to go into a little support roller oil.Before directly adding cooling water in the bearing bush of supporting roller, oily temperature will drop to below 60 ℃.
The invention has the advantages that creatively and adopt " machine dissolves water with fabric disc+oil and grinds a watt method " to carry out emergency processing, the timesaving is little to the damage of axle simultaneously.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Fig. 1 is an overall structure front view of the present invention;
Fig. 2 is an overall structure left view of the present invention.
The specific embodiment
There is tugboat axle 3 at rotary kiln 2 two ends, and tugboat axle 3 belows have bearing bush of supporting roller 1 to be used for supporting and the location.Fuel outlet is arranged at the bearing bush of supporting roller bottom.Embodiment 1
The method step that rotary kiln of the present invention is repaired fast is following, and step 1 directly adds cooling water in the bearing bush of supporting roller 1, lets tugboat bearing shell 1 temperature reduce to 40 degree, and perhaps 30 degree, 35 are spent temperature, as long as till accomplishing to make things convenient for the workman to operate; Step 2 is earlier carried out scraping with triangular scraper with indivedual peaks of the face metal protuberance layer of 3 of support rollers, installs machine with the handhold mini-size polishing machine then and polishes with fabric disc again, and is smooth, smooth until what polish the axial plane metal protuberance layer of support roller 3; Step 3 utilizes oilstone under rotary kiln 2 slow-speeds, supporting-roller shaft to be carried out lappingout, till being smooth to the touch; Step 4,2 dozens of slow-speeds of rotary kiln continue to bearing bush of supporting roller 1 in, to add cooling water, and it are oily to drench a little support roller simultaneously, 3 hours time, perhaps 1 o'clock, 1.5 hours also can, up to reaching cooling effect; Step 5, inspection are confirmed in the bearing bush of supporting roller 1 to add the bigger support roller of viscosity with oil behind no any foreign matter, rotary kiln 2 production that feeds intake, and the fast and inventory of kiln slowly increases up to returning to normal production.
The present invention directly adds cooling water in the bearing bush of supporting roller 1, need new tugboat oil be injected from observation panel before, simultaneously opens bearing bush of supporting roller 1 fuel outlet, reduces to 60 degree until temperature, 50 degree or 45 spend also can, make things convenient for the workman to operate till.The handhold mini-size polishing machine is installed machine and is polished with fabric disc, and it is inhomogeneous to prevent to polish, the axle of damage support roller 3.Rotary kiln 2 cools off under the slow-speed state, refers to the cooling of bearing bush of supporting roller 1 water, grinds, and in water, drench to go into a little support roller oil.The rotary kiln slow-speed refers to Revolution Per Minute one commentaries on classics, two change also can, a horizontal polishing speed when changeing can be hurried up, rotating speed is fast, laterally the speed of polishing can be hurried up.The fabric disc polishing is to use coarse sand earlier, uses fine sand again.
